Application led September 25, 1908. Serial No. 454,743.

To all whom 'it may concern:-

Be it known that'we, ROBERT J. SMY'rH, a citizenfbf Canada, and FRANKALLiNGEii, a citizen of the United States, both residing at Yerino, inthe-county of San Bernardino and State of California, have invented newand useful Improvements in Hydrocarboni Burners, of which the followingis a specilicay whereby both steam and air are thoroughly mixed withhydrocarbons before they are trsciia-r' ed, from the burner tip. Theoriltice in e'burner tip is of a considerable less diameter than themixing tube which feeds thfu-el to the said burner tip, which is formedofa gradual tapering point in such -manner as t'o produce a backpressure inthe supply pipe.

the accompanying drawings, forming a partlof this specification F' ure 1is a vertical longitudinalvsection o .the burner.

Which is controlledjb'y valve8.. Avnozzle '9.of double cone shape i's's'crewe'd into the'lower end oibod '5 this nozzle'bei'ng of-sulficient capacity lthe. burner. A pipe 10connects With the outer'eiid of nozzle 9- and ends in a burner tip v11.which may be at any conveni'eiit distance from the burner itself;Within lilod'ylra nozzle 12 is' arranged projecting required oi?throught-chamber 6 and discharging into, n

air beyond the said oil admission means,

nozzle .9. 'The up er end of nozzle 12 connects with a cham er 13 formedin body 5, chamber also being connected by ports 14 to. the atmosphere.chai/uber 13 is' a steam nozzle 15 which is sup led with 'steam througha' pipe 16 con- .tro ed by valve 17.

'In' the operation of this burneran appropriate volume of steam is'admitted to nozzle 15 and-is discharged therefrom directly into so thatthey may be burned eli'ithrouuh nozzle l2l from ports 14. 'llieProjecting into g mixe volume of steam and air passing through 12 isagain discharged expansively into nozzle 9 .and oil from pipe 7 is drawnthrough the nozzle in a volume regulated by valve 8. The volume of oil,steam and air discharged from nozzle 9 into pipe 10 is' thoroughly mixedand atomized on account of the velocity of the steam issuing from nozzle15 and produces in the pipe 10 considerable pressure on account of thisvelocity and the condensation of the steam. This pressure enables thefuel to be led to points quite a distance from the burner instead ofbeing'necessarily discharged from the burner tip immediately adjacenttheburner. On this account the burner may be placed away from theV flameso that itis possessed vof a much longer life than the averagerburnernot being subjected to the intense heat of iinmediate exposure' to 'theflames. Being conveniently 'removed from the immediate vicinity of theflame one burner may suffice for feeding a pair of furnacesthus reducingexpense yfor both installation and mainte nance.

We claim:-

1'. In a hydrocarbon burner the combination of a body portion, a steampipe tei-ininating in a nozzle in said body portion, said body portionbeing formed with air ports adapted to admit air above the Vterminaloint of 'said nozzle, a second nozzle in said ody'portion, said nozzleshaving bores of 'substantially the same diameter, an oil inlet adaptedto admit oil above the termination of said second nozzle, and a thirdnozzle b means of which the mixture of steam, air and oil are ejected,to a burner tip.

2. In a hydrocarbon burner in combination, a body portion, a steamnozzle, means to admit air aroundI said steam nozzle, means to admit oilinto said body portion, means to conduct said ,mixture of steam andmeans so formed as to mix the oil With said mixture of steam and air,and means lto deliver said mixture ot steam, air' and oil to a `burnertip, said burner tip being formed of a nozzle 12, drawing atmosphericair with it l adapted touse said stearato draw air into havia hereuntosubscribed our names this Sth day of September, 1908.

{OBERT J. SMYTH. FRANK ALLINGER.

said body portion, a second @spil-ating means adapted to use the mxturfof :ato/:Lm and air, f to dmw oil into mid bmly portion, said aspiratingmeans comprisingnozzles having bores of substantially the sainediameter, and menus to deliver said mixure of steam, air and oil to aburner tip.
